How to work it out

  1. Turn the percentage into a decimal: 9 ÷ 100 = 0.09
  2. Multiply: 0.09 × 28 = 2.52
  3. Check: Work backwards: 2.52 ÷ 28 × 100 = 9%.

Another method. As a proportion of part to whole: 9/100 = part/28, so part = 9 × 28 ÷ 100 = 2.52. Both methods always give the same answer.

In a spreadsheet: =9%*28. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

2.52 is the 9% share of 28. The remaining 91% is 25.48, and the two parts add back up to 28.

Discounts: 9% off an item priced $28 saves $2.52, so you pay $25.48.

Adding and taking away 9%

Increasing 28 by 9% gives 30.52 and decreasing it by 9% gives 25.48. These do not cancel out: raising 28 by 9% and then lowering the result by 9% ends at 27.7732, because the second 9% is taken of a bigger number.
